EVALUATION OF SELECTED INSECTICIDES FOR CHINCH BUG CONTROL ON A BUFFALOGRASS LAWN, 2001

Influence of buffalograss management practices on Western chinch bug and its beneficial arthropods.

A 2-yr study was conducted to document the influence of selected buffalograss, Buchloë dactyloides (Nuttall) Engelmann, management practices (three mowing heights and five nitrogen levels) on the seasonal abundance of the western chinch bug, Blissus occiduus Barber (Heteroptera: Lygaeidae), and its beneficial arthropods. Vacuum, pitfall, and sticky traps samples were collected every 14 d from t...

Chinch bug-resistant buffalograss: an investigation of tolerance, antixenosis, and antibiosis.

Choice and no-choice studies were conducted to determine the categories (antibiosis, antixenosis, and tolerance) of resistance of four buffalograsses (NE91-118, 'Bonnie Brae', 'Cody', and 'Tatanka') previously identified as resistant to the western chinch bug, Blissus occiduus Barber. Antibiosis studies found no significant differences in western chinch bug fecundity, nymphal development, or su...

Resistant Turfgrasses for Improved Chinch Bug Management

Evaluation of Buffalograss Germplasm for Resistance to <i>Blissus occiduus </i> (Hemiptera: Lygaeidae)

Blissus occiduusBarber has emerged as an important insect pest of buffalograss,Buchloë dactyloides (Nuttall) Engelmann, in Nebraska. This research evaluated selected buffalograss germplasm for resistance to B. occiduus. Eleven buffalograss selections were screened for chinch bug resistance in three greenhouse studies and two Þeld evaluations. Based on chinch bug damage, NE91Ð118, ÔTatankaÕ, ÔBo...

Transcriptional Profiling of Resistant and Susceptible Buffalograsses in Response to Blissus occiduus (Hemiptera: Blissidae) Feeding.

Understanding plant resistance mechanisms at a molecular level would provide valuable insights into the biological pathways impacted by insect feeding, and help explain specific plant tolerance mechanisms. As a first step in this process, we conducted next-generation sequencing using RNA extracted from chinch bug-tolerant and -susceptible buffalograss genotypes at 7 and 14 d after chinch bug fe...
